Seems like it wouldn’t have a place in jiu jitsu, right? Having an imagination? Believe it or not there really does have a place in jiu jitsu. You have to be able to imagine what your attempting and the most likely reaction to it. It’s the ability to visualize not just what you are doing now, but the most likely sequence of actions that will follow between you and your partner.

It’s ok if you don’t see that progression now, particularly if you’re at a lower belt. That sort of imagination/visualization comes with time and practice: you start to see the opportunities to act on the techniques you imagined yourself performing. But, as I said, it takes time and practice in order to hone that skill.
